Thanks all.
Once the clouds cleared early in the evening , the sky was quite dark, we have dad days of showers/rain, so it would have cleaned out the atmosphere nicely. There is a rediciously bright set of floodlights some Kms away to the NNE, for the railway, casting a big orange skyglow upwards, but once the comet climed out of that, the sky background was not too bad. I kept imaging it as it transited, till it was about to dissapear behind a small tree.
I note there is now no trace of any ion halo/tail, possibly related to the recent disconnection event?
I had polar alingment very close, I was able to spot Octans and this trianglular astrism of stars that rotate about the south celestial pole, and rotate the RA axis and see the stars rotate about the same area. After a small tweak using drift aligning, I was able to go for each 5 min image without touching the RA.
The light pollution did cause a strong gradient that I removed with a combination of the remove gradient feature in Iris, and Gradient Xterminator plugin in Photoshop. Flatfield was taken using this spiffy new lightbox that Houghy built.
